Prezados colegas,

 

O destaque desta edição via sem dúvida para a primeira espécie anunciada
Poeciliopsis prolifica.

O texto diz tudo o que há para comentar.

Esta espécie não necessita de aquários aquecidos dentro de casa, mas não
convém mantê-los ao ar livre todo o ano, nomeadamente se as temperaturas
mínimas descerem abaixo dos 10ºC.

Embora não possua dados suficientes sobre a biologia e sobre as exigências
térmicas desta espécie, devemos assumi-la como subtropical, pelo que a
mínima fornecida é uma estimativa feita de acordo com o clima da vasta
região de distribuição geográfica, logo, sem base científica ou experiência
própria.

Ainda assim é uma interessante opção para quem tenha aquários entre os 25
litros e os 60 litros de capacidade, sendo um peixe totalmente compatível
com outras espécies e mesmo com camarões e outros invertebrados.

Enfim, uma boa razão para contactarem com uma loja que trabalhe com este
fornecedor.

 

 

Um abraço

 

Miguel

Poeciliopsis prolifica -  Blackstripe livebearer

 
<http://www.aquariumglaser.de/backend/FCK/UserFiles/Image/News-Pics/kw%2039%

This tiny species of livebearer originates from northwestern Mexico. The
males reach a maximum length of 2 cm, the females of 3.5 cm. At the first
glimpse the fish look somewhat unspectacular, but no one who keeps the fish
has regrets about it. The whole day through the males are after the females
or fight their harmless clashes. When doing this they swim in a typical
head-down position and spread the gonopodium in an 90° angle from the body.

This minuscule fish fits perfectly for nano tanks. Regarding the water
chemistry they are completely undemanding. In nature they are even found in
brackish waters. It is possible to keep this peaceful species in a community
tank, but they do much better in a species tank.

It is very interesting that the young are not born at a time, but over a
period of several days. So a person, who observes this, could get the idea
the fish would give birth every day. This is why the species got its name.

Lexicon: Poeciliopsis: means "similar to Poecilia". prolifica: means
"prolific", refers to the fact that the females give birth over a number of
days. Gonopodium: name for the modified anal fin of male livebearers which
serves as a copulation organ.

Umbra pygmaea

The mudminnows (Umbra) are relicts from the ice age and nowadays found only
in remainings of their initial territory. Three species are still extant,
two of them in North America and one in Europe. The European species (U.
krameri) is in danger of extinction due to habitat destruction.

Mudminnows are inhabitants of extreme biotopes: swampy areas with changing
oxygen content, gross temperature differences and very low pH. In former
days they were popular aquarium fish. Today mudminnows are among the
absolute rarities in aquaria due to their unspectacular coloration.

Even if it doesn´t look like it: mudminnows are relatively close relatives
to pikes (Esox). However, they stay much smaller, reaching hardly 10 cm.
Most of them stay even smaller than this. Mudminnows can breath through
their swimming bladder and so they can take all oxygen they need from the
air.

We can offer now Umbra pygmaea as German bred. The species originates from
North America, but can be found today in larger parts of Europe, too, where
it has been released. U. pygmaea is very similar to the endangered U.
krameri and so many reports for U. krameri may refer in truth to the
introduced species. Even if it was as long ago as before 1913 that U.
pygmaea was released in German waters, one should always keep in mind that
it is absolutely forbidden to release any animal from captivity in the wild,
may it be a member of a foreign or a native species.

Mudminnows can be kept very easily in captivity. They fit both for aquaria
and garden ponds. It is good for them if peat as ground is offered. Heaters
are not only unneeded, but even harmful. Mudminnows are thus perfect fish
for people who have to save electricity. They feed readily on any kind of
frozen and live fishfood. Sometimes they can be quarrelsome to conspecifics,
so the tank should have a lot of hiding places.

Females grow bigger than the males. Mudminnows take parental care. Females
built nests between dense vegetation and tend very aggressively eggs and
larvae. For breeding it is necessary to hibernate the fish at low
temperatures (4-8°C, less than 8 hours light per day). They start spawing at
13°C and longer photo periods.

Lexicon: Umbra: Latin, means "shadow", refering to the dull coloration.
krameri: dedication name. pygmaea: Latin, means "dwarfish".

Corydoras from the Rio Jamanxim - C. bifasciatus?

 
<http://www.aquariumglaser.de/backend/FCK/UserFiles/Image/News-Pics/kw%2039%
202009/jamanxin%20longnose%20glaser.jpg> 

>From the Rio Jamanxim in the state of Pará, Brazil, we received for the
second time now beautiful Corydoras catfish.  The Rio Jamanxim is a tribute
to the Rio Tapajós. The first shipment of corys from there contained only
long snouted animals, whereas the second shipment contained the shortsnouted
counterpart.

 
<http://www.aquariumglaser.de/backend/FCK/UserFiles/Image/News-Pics/kw%2039%
202009/jamanxin%20shortnose%20pair%20glaser.jpg> 

The new corys remind one to Corydoras ornatus, C. parallelus, C. pulcher,
and C. schwartzi, as well as the  C-numbers C133 and C141. Like all of them
they have a pattern of two bold black stripes, a black band through the eye
and a golden shining saddlespot before the dorsal fin origin. However, C.
ornatus, C. pulcher, C. schwartzi, and C141 have a black pattern in the
caudal fin, whereas our new ones have hyaline caudals. C. parallelus as a
black triangle-spot situated directly under the dorsal fin origin, which is
not found in the Jamanxim fish. 

Corydoras bifasciatus is not known until today alive. Preserved ones show a
hyaline caudal fin and belong to the longsnouted group of Corydoras. The
type locality of C. bifasciatus is in the upper Rio Tapajós system, so it is
very likely that our fish from the first shipment really belong to the
species C. bifasciatus. The shortnoses from our second shipment already have
received the C-number C133. They belong to a species new to science.

Text & photos: Frank Schäfer

Lexicon: bifasciatus: means "with two stripes". ornatus: means "splendid";
parallelus: allusion to the two black parallel stripes on the flanks;
pulcher: means "beautiful"; schwartzi: in honour of Willy Schwartz, an
exporter of ornamental fish.
